' This invention relates to adjustable test regating the stack of the buildingirom the segregated from other parts thereof as for instance the bath tub connections and trap in conjunction therewith are required to be tested separately from the stack to which the This invention seeks to provide a means which enables'the outlet of the trap in such portion of the system as is connected with the bath tub to be closed or sealed to the rebe independently made of the trap and bath tub connections and as is hereinafter more fully described, the particular form of the adjustable connection which is the subject 35 matter of this invention depends largely upon its position of use but the principle involved is identical in any of the possible forms which may be employed, two of which are shown herein. These and other objects and gland may be removed and a .single plug such as is shown in Fig. 3 is screwed into the member 12 against the packing therein to seal the said hub.

These tests are usually made before conr.

pletion. of the buildingthat is,'while the walls are unplastered and. the plumbing ac- I cessibleand. thus'thewhole system is put in place and with the hub 12 provided with the closure plug. When the system has been erected and in conditionto be testedthis plug-- is removed and my adjustable connector put in place as. in th'e'm'ann'er described:
